I believe you can speed it up even further if the tags with classes are
in a div that has an ID.
$("#divID tag.class")
This way the dom traversal is limited to only that section of the document.

if the elements you search for are all of the same type (eg. div),
it's much faster to include the tag, because without the tag jquery
would have to search through all elements on the page to find the
elements with the corresponding class, instead of just searching
through the divs..

Erik I was under the impression that the exact opposite was true for
searches by class: that including the tag slows it down.
I may be mistaken, you'd have to check the list archives or perhaps
check the script, I may do the same tomorrow.

ID is found by using document.getElementById(), which is probably
about as fast a DOM operation as can be had. Use ID for sure.
Also, if I'm not mistaken, it helps class searches a lot if you also
include the tag that you're looking for: $(' div.someClass')
instead of
just $('.someClass').
